External power arc tests

Introduction

The external power arc tests are carried out by the High Power Laboratory (AP2), located in the Adrianópolis Unit. They aim at verifying the withstanding capacity of insulators and insulator strings when submitted to external power arcs resulting from phase to ground fauilures. The satisfactory performance of equipment under such conditions is important to the security of the electric system and the continuity of the energy supply.

 

The tests performed by AP2 are suitable for high voltage equipment. To this end, the laboratory has the infrastructure to provide voltages and currents and meet the specificities of the clients and/or the test standards, within the limitations of the laboratory, for example: calibrated measurement systems; switches and circuit-breakers for current establishment and interruption; current limiters; protection systems and suitable current and voltage sources.

 

The main clients of these tests are: electricity utilities and equipment manufacturers.
